It's been awhile since I've posted on this site around my electrical issues. I have cut my hole (it required a 2 7/8" hole saw) & I was limited to a 2 1/2" without having to go buy one. So I had to file out the difference. I ran my line through the floor & out to avoid having to go through the double skin & insulation. First attempt wasn't quite what I was looking for. After careful (evidently not) measurements I ended up drilling a hole thru the floor into one of the cross members underneath. Squarely in the middle of it, no damage at all just a hole perfectly centered.

Sure hope there isn't any deadly critters living in it. No wonder I couldn't see light thru the hole. Moving over a couple in inches I was in business. I still need to cover up the first hole in the floor.
I've been plugged in now for a few weeks & so far all is well. As I am in a temporary location I have had to run an adapter down to 20A & plug into one of the house plugs. This is limiting my capabilities. I currently have my 4 cu ft fridge running .4A running power, a coffee maker, my Bose system OR a small TV with Roku or DVD. Not all at once, music while I'm up & TV when I go lay down. I also keep my laptop & hotspot charging at all times. I bought LED light bulbs for the two lights I have plugged in. I couldn't find 25W so I bought 40W. Since then I have one 25W & one 40W. Plenty of light for me. Wow, when I list all I am running at the moment it sure does seem like I'm already overdoing it.
I used my NuWave PIC on board the other day & before I even plugged it in & turned it on I shut the circuit to the fridge for the duration. Maybe a 15A circuit could handle all of that but I don't see any need currently to try.
I got the two trees that are blocking my way to moving the bus down back cut down yesterday. Now I need to find someone to come haul off the trees for firewood. I offered them up for free on FreeCycle.org so I'm gonna have to wait & see if I get any takers. If not, I'll just need to cut them slightly shorter for a bobcat to chunk them over the banking. I hope it doesn't come to that as they two nicely sized white oaks.
I bought me a Mr Heater Big Buddy as I don't want to deal with anything larger than 20# tanks & I bought a 50ft 10/3 extension cord that is plugged into where the washing machine was, I unplugged it & plugged in the ext cord for running an infared heater for times I'm not running the propane.
All in all I'm doing the best I can to stay comfortable out here without burning the house & bus down.
